what sound decoder ?
you can either use a cam which is a thin etch with a pick-up or use DDE (Dynamic Digital Exhaust) this is normally set-up in Cv 51- Cv 56 on soundtraxx decoders.
If you visit the Soundtraxx site you can download their manual which gives more detail. If you use Soundtraxx I'll post you my settings off list only.
